D2 (and Webtop and xCP) CTF

CTF (Content Transfer Framework) is how EMC Dell calls their “new UCF”. It works as a browser extension, and is the same extension you’ve used for the latest version of Webtop (new functionality getting first to Webtop? LOL). And this mode is not the default (why?) so you’ll need to change it in the settings.properties file of D2.

Also, this extension will generate some “index” files on the folder where you download files:

  • .checkout.xml
  • .d2_edit_storage.json
  • .d2_view_storage.json
  • .view.xml

That contain object names, ids, operation performed, and folder paths of the files transferred.

Tested on latest Firefox Nightly x64 and Chrome.

FYI, I’m pasting the “wonderful” ASCII compatibility matrix provided by Dell in the configuration file:

#     +——————-+——+——+——+——+
#     | Browser:OS \ Mode | Thin | Java | ctf  | Note |
#     +——————-+——+——+——+——+
#     | IE 11             | yes  | yes  | yes  |      |
#     +——————-+——+——+——+——+
#     | Edge              | yes  | NO   | NO   | (1)  |
#     +——————-+——+——+——+——+
#     | Firefox           | yes  | yes  | yes  |      |
#     +——————-+——+——+——+——+
#     | Chrome            | yes  | NO   | yes  | (1)  |
#     +——————-+——+——+——+——+
#     | Safari:Mac_OSX    | yes  | yes  | yes  |      |
#     +——————-+——+——+——+——+
#     | Safari:Mac_IOS    | yes  | NO   | NO   | (2)  |
#     +——————-+——+——+——+——+
# Notes:
# (1) Chrome and Edge do not support java applets, and Edge does not support the CTF plugin.
#     D2 will fallback to thin client mode appropriately when java or ctf has been
#     specified in the value of the browser.plugin.mode setting as described above.
# (2) If browser.plugin.mode contains java or ctf, then D2 will silently continue to run in
#     thin client mode. Safari running on Mac_IOS does not support the java or ctf plugin.

  1. The D2 and xCP are not java based for both windows and mac solution.
    D2 and xCP never used UCF and hence could rewrite the java applet logic.
    It packages the code and the python runtime along with required libraries into a executable.
    So you will see CTFNativeApp.exe in your task manager for both D2 and xCP. Its the common binaries shared between the d2 and xCP.
